The adapter plate is CNC machined by a water jet from rigid 1/8” thick aluminum with dimensions that covers up the hole in the firewall after you remove the power booster. This modification will clean up your firewall by getting rid of the big, bulky power booster. Racers do this swap when their engine does not make enough vacuum to operate the power booster, to shed a few pound to make their car lighter, or to clean up the engine bay. The pro-touring fans use manual brakes to get a better “feel” of their brakes when heading into a corner at a high rate of speed. The adapter plate can also be polished up to a mirror finish if needed.

The firewall brace plate is CNC machined by a water jet from rigid 1/2" thick aluminum with dimensions that extend out over the contours of the stamped firewall to dramatically reduce the flex associated with third generation (1982-2002) F-body Camaros and Firebirds.

A two inch hole will have to be added to your firewall between the two upper holes that the vacuum booster bolted to. The extra hole in the firewall allows for the high 6 to 1 pedal ratio.

A hole will have to be drilled into the brake pedal arm to accept the supplied stud for the adjustable pushrod assembly which is normal for any manual brake kit you buy.

Kit comes with a gasket matched to the adapter plate to seal the passenger compartment from the engine bay. The other kits do not offer a gasket in their kits.

Kit comes with a dual bolt pattern to run different master cylinders from GM, Ford, and MOPAR. The other manual brakes kits do not have this feature.

Kit comes with a under dash brace that is included in the kit and reduces firewall flex dramatically. The other manual brake kits offer this at an additional cost.

Kit comes with the correct size master cylinder that is matched to the size of the front and rear brakes. The other manual brake kits offer a larger bore master cylinder which generates less brake line pressure.

Parts to Enhance Your Manual Brakes on Your F-body:

NON Low Drag Caliper (see below) - These type of calipers are mandatory to work with the supplied 7/8" bore master cylinder.

New Rubber or Stainless Steel Flexible Brakes Lines (front and rear) - Old rubber lines will "balloon" causing loss of pressure within the braking system.

LOW Drag Calipers

LOW drag calipers came on all third generation F-bodies with the standard (NON 1LE) front brake systems. These same calipers came on 1982 -1988 G-bodies (Monte Carlo, Regal, Cutlass) and 1982-1997 S10 trucks and SUVs.

All replacement calipers should be rebuild to NON low drag (normal) specifications. They rebuild them this way so they will work with both step bore master cylinders and strait bore master cylinders. LOW drag calipers are designed to work with a step bore master cylinder and will not work with a strait bore master cylinder.
